Case Facts
The claimant, Scotson, was a shipowner who had entered into a charterparty — a contract for the carriage of goods by sea — with certain third parties. Under that charterparty, Scotson agreed to carry a cargo of coals and deliver it to the order of those third parties in exchange for freight. The third parties subsequently sold the coals to the defendant, Pegg, and directed Scotson to deliver the cargo directly to him.
In consideration of Scotson delivering the cargo to him, Pegg entered into a separate agreement with Scotson, promising to unload and discharge the coals at the rate of forty-nine tons per working day once the ship was ready to unload. Pegg failed to perform this obligation. He discharged the cargo at a slower rate than agreed, causing a delay of five days beyond the period within which he ought to have completed the task. As a result, Scotson incurred expense in maintaining the master and crew of the vessel during the additional period.
Scotson brought an action against Pegg for breach of the discharge agreement. Pegg responded by way of a plea in demurrer, arguing that his promise was a nudum pactum — a bare promise unsupported by consideration — on the ground that Scotson's delivery of the coals was nothing more than the performance of a pre-existing obligation already owed to the third parties under the charterparty. Since Scotson was already legally bound to deliver the coals, Pegg contended that this act could not constitute fresh consideration to support his own promise.
Held
The Court of Exchequer, deciding the matter on the demurrer on 28 January 1861, held that Pegg's plea disclosed no valid defence in law and was bad both on principle and in law. Judgment was entered for Scotson. The court rejected the argument that performance of a pre-existing duty owed to a third party cannot constitute good consideration for a promise made by a different party who derives a benefit from that performance.
Ratio Decidendi
The foundational principle established by this case is that the performance of an act which a party has already agreed to perform under a prior contract with a third party can constitute valid consideration to support a new and separate contract with a different party, provided that the new contracting party derives a benefit from that performance.
The first limb of the ratio focuses on benefit to the promisor. The court articulated the governing principle in the following terms: any act done whereby the contracting party receives a benefit is good consideration for a promise by him. In this case, the delivery of the cargo of coals to Pegg plainly conferred a benefit upon Pegg. That benefit was sufficient to sustain his promise to discharge at the agreed rate, notwithstanding that Scotson was simultaneously bound under the charterparty with the third parties to make the very same delivery. The court held it to be entirely immaterial that Scotson had previously contracted with third parties to deliver the coals to their order. What mattered was that Pegg received a benefit from the delivery.
The second limb draws a critical distinction within the doctrine of consideration as it relates to existing duties. This case is concerned with an existing duty owed to a third party, which the court held can be good consideration for a promise made by a different contracting party. This stands in contrast to the rule applicable where a party seeks to enforce a promise in exchange for performance of a pre-existing duty owed to the very same promisee. In the latter situation — illustrated by the sailors' wages scenario discussed in argument — the courts have generally held that performance of an existing duty owed to the same contracting party cannot constitute fresh consideration. The court in this case distinguished that line of authority and declined to apply it to the present facts. The rule in this case is therefore that the relevant question is not whether the act was already owed to someone, but whether the defendant obtained a benefit from it.
The principle stated in the headnote of the report encapsulates the ratio: "The performance of an act which a person has agreed with another to perform, is a good consideration to support a contract with a third person if the latter derives a benefit from the performance."
This case forms part of a wider framework of cases addressing the doctrine of consideration, alongside cases such as Stilk v Myrick [1809], which governs the distinct situation of duties owed to the same contracting party, and Williams v Roffey Bros [1991], which later developed the practical benefit test in the context of variation of existing contracts.
Obiter Dicta
Two obiter observations of significance emerge from the judgements in this case.
First, it was noted that it is entirely consistent with the declaration that there may have been a dispute as to the defendant's right to the coals at the time of the agreement, or alternatively that Scotson may have detained the cargo pending recovery of demurrage owed under the charterparty. Either of those circumstances would have independently supplied good consideration for Pegg's promise, entirely aside from the actual delivery itself. These scenarios were not proved at trial but were identified as legally sufficient bases upon which consideration could have been grounded.
Second, in a separate judgement, it was reasoned that the mutual promises exchanged between the parties were themselves each capable of serving as consideration for the other. Scotson's promise to deliver the cargo and Pegg's promise to discharge at the rate of forty-nine tons per working day were reciprocal obligations, each providing consideration for the other in the conventional bilateral sense. This reasoning offers an alternative analytical route to the same conclusion, grounding the validity of the contract in the exchange of mutual promises rather than exclusively in the benefit derived by Pegg from the physical act of delivery.
